HS Series Specifications

The HS Series features an integrated heatsink, which makes them so cool. Because there is less thermal resistance internal to the

unit than in a standard SSR mounted to the same heat sink, heat dissipates more easily. The built-in heatsink means you don't

have to select a heatsink, and installation is much easier. Each HS-series SSR has built-in hardware for screw mounting and a built-

in DIN-rail adapter clip for mounting to a 35mm DIN rail.
